The oM SE-MJ5 is a mid-range pair of on-ear headphones in Pioneer's "DJ-inspired" line. Aimed at mainstream consumers seeking a step up from basic headphones without spending well over $100 on a professional model, the SE-MJ5 utilize 40mm drivers and feature Deep Bass sound tuning for a more powerful lower end. They are compact and easy to carry thanks to a folding, single-cord design. And they include a 2m extension cord and carry pouch. The 50mm SE-DJ5000, Pioneer's entry-level DJ headphones, are a step up, featuring a more durable build and single-ear monitoring support.
